Process for production of aluminum

摘要

Disclosed herein is a process for producing aluminum of high purity by the steps of electrolyzing an electrolytic bath composed preponderantly of aluminum chloride or aluminum bromide for thereby educing aluminum on the cathode, causing the cathodic product of electrolysis to precipitate to the bottom of the electrolytic cell, then melting the precipitate to produce molten aluminum, casting the molten aluminum into ingots and cooling the ingots.
